Regrets, he’s had a few. Seven months after revealing his HIV-positive status, Charlie Sheen sat down for a follow-up interview on the Today show to discuss his life after going public with the diagnosis.

“It was like being released from prison,” he told Matt Lauer on Tuesday, June 21, of announcing in November 2015 — approximately four years after he was diagnosed — that he’s HIV-positive.

“I regret not using a condom the one or two times when this whole thing happened,” he explained. “I regret ruining Two and a Half Men. I regret not being more involved in my children’s lives growing up, which I am now. That’s about it. We can only move forward from today. They wouldn’t call it the past if it wasn’t.”

The Anger Management actor, whose role as Charlie Harper on Two and a Half Men was loosely based on his signature bad boy image, starred on the hit CBS sitcom for eight seasons. During his run, he received four Emmy nominations and two Golden Globe nominations and was the highest-paid actor on television at the time.

In January 2011, Two and a Half Men went on hiatus when Sheen entered a substance rehabilitation program. Two months later, he was fired from the gig after publicly making disparaging comments about the series’ creator, Chuck Lorre. He was replaced by Ashton Kutcher for the final four seasons.

The father of five also revealed on Tuesday that he didn’t share his HIV-positive status with some of the women he slept with after his diagnosis. He insists, however, that “no one has been infected” and that the virus is now “undetectable” in his blood.

“There was two examples, but protection was always in place, and it was for the right reasons because everyone that I had told up to that moment had shaken me down,” he said.

As previously reported, Sheen is currently under investigation by the LAPD after he allegedly threatened his ex Brett Rossi.
